Width-adjustable storage module for cabinets

A method of installing functional and customized storage into an existing cabinet defining a storage space, comprising:

• providing an expandable frame adjustably expandable to fit the storage space, the frame having cross members and uprights defining U-shapes, the cross members being adjustable in length to at least a narrow-width position and a wide-width position;
• providing extendable glides attached to the uprights at top and bottom positions on each side;
• providing a laterally-expandable pullout module operably mounted on the glides for movement, the pullout module having right and left half-basket portions connected by connectors, each half-basket portion having a half floor and a fence extending around three sides of the half floor, and the connectors permitting lateral adjustment of the basket portions selectively to the narrow-width position and the wide-width position;
• assembling the expandable frame into the existing cabinet including expanding the expandable frame to fit the defined storage space;
• attaching the glides at a desired height to the expandable frame;
• and
• adjusting a width of the pullout module and then attaching the pullout module to the glides to provide a pullout storage function.
